Mayankho a mavuto ogwiritsa ntchito galasi lotsekera m'nyengo yozizira

Chifukwa cha kutentha kochepa m'nyengo yozizira, ndi mavuto otani omwe mungakumane nawo mukamagwiritsa ntchito galasi lotsekereza pamalo otentha pang'ono? Ndipotu, galasi lotsekereza ndi guluu wochiritsa kutentha kwa chipinda womwe umakhudzidwa kwambiri ndi chilengedwe. Tiyeni tiwone momwe guluu wagalasi amagwiritsidwira ntchito m'malo otentha pang'ono m'nyengo yozizira. Mafunso atatu ofala!

1. Pamene galasi lotseka likugwiritsidwa ntchito pamalo otentha kwambiri, vuto loyamba ndi kuzizira pang'onopang'ono

Kutentha ndi chinyezi cha chilengedwe zimakhudza kwambiri liwiro lake lotha kuuma. Pa zinthu zomatira za silicone zomwe zimakhala ndi gawo limodzi, kutentha ndi chinyezi zikachuluka, liwiro la kuuma limathamanga kwambiri. M'nyengo ya autumn ndi yozizira, kutentha kumatsika kwambiri, zomwe zimachepetsa liwiro la kuuma kwa silicone sealant, zomwe zimapangitsa kuti nthawi youma pamwamba ichepe komanso kuuma kwambiri ikamauma. Nthawi zambiri, kutentha kukatsika kuposa 15°C, liwiro la kuuma limakhala lochepa. Pa khoma la nsalu yachitsulo, chifukwa cha kuuma pang'onopang'ono kwa sealant nthawi ya autumn ndi yozizira, pamene kusiyana kwa kutentha pakati pa usana ndi usiku kuli kwakukulu, mipata pakati pa mbale idzatambasulidwa kwambiri ndikukanikizidwa, ndipo sealant yomwe ili pamalo olumikizirana idzatupa mosavuta.

2. Chotsekera galasi chimagwiritsidwa ntchito pamalo otentha kwambiri, ndipo mphamvu yolumikizirana pakati pa guluu wagalasi ndi substrate idzakhudzidwa

Pamene kutentha ndi chinyezi zikuchepa, kugwirizana pakati pa silicone sealant ndi substrate kudzakhudzidwanso. Kawirikawiri yoyenera malo omwe silicone sealant imagwiritsidwa ntchito: zigawo ziwiri ziyenera kugwiritsidwa ntchito pamalo oyera pa 10°C~40°C ndi chinyezi cha 40%~60%; gawo limodzi liyenera kugwiritsidwa ntchito pa 4°C~50°C ndi chinyezi cha 40% ~60% m'malo oyera. Kutentha kukakhala kochepa, liwiro la kuchiritsa ndi kuchitapo kanthu kwa sealant kumachepa, ndipo kunyowa kwa sealant ndi pamwamba pa substrate kumachepa, zomwe zimapangitsa kuti sealant ikhale yogwirizana bwino ndi substrate.

3. Chotsekera galasi chimagwiritsidwa ntchito pamalo otentha kwambiri, ndipo guluu wagalasi umakhuthala

Pamene kutentha kukuchepa, silicone sealant imakhuthala pang'onopang'ono ndipo kutulutsa kwake kudzakhala kochepa. Pa zomatira ziwiri, kukhuthala kwa gawo A kudzapangitsa kuti kuthamanga kwa makina a glue kuchuluke, ndipo kutulutsa kwa guluu kudzachepa, zomwe zimapangitsa kuti guluu asakwanire. Pa chomatira chimodzi, colloid imakhuthala, ndipo kuthamanga kwa extrusion kumakhala kwakukulu panthawi yogwiritsa ntchito mfuti ya glue pamanja kuti muchepetse kugwira ntchito bwino kwa manja.

Momwe mungathetsere

Ngati mukufuna kumanga pamalo otentha pang'ono, choyamba yesani guluu waung'ono kuti mutsimikizire kuti guluu wagalasi ukhoza kuchiritsidwa, kuti uli bwino, ndipo palibe vuto lililonse lomwe lingawonekere musanamange. Ngati zinthu zilola, choyamba onjezerani kutentha kwa malo omangawo musanamange.
